This white paper reviews the challenges with endpoint security in virtualized environments - including the inherent risks of dynamic virtual machines and the resource impact of security software such as virus-scanners in multiple guest virtual machines, on a single physical host.

This white paper describes the evolution of these changes as enterprises adopt virtualization and then cloud computing. It then describes Trend Micro's vision for the evolution of security as a facilitator of mobility, virtualization, and cloud computing.

With thousands of new malware threats being created and unleashed into the Internet daily, the End Point security model is failing. Without additional layers of security, infiltration may be virtually impossible to stop. This important white paper explores alternatives that eliminate dangerous traffic prior to reaching the network or server.

Spam looks like a simple enough issue until you have to try to define it: after all, we all think we know it when we see it. Most people have a working definition along the lines of “email I don’t want.” While that’s perfectly understandable, it is difficult to implement technical solutions based on such a subjective definition. Read this paper to learn why SPAM is more than just unwanted email.

Anti-virus does much more than reactively detect known viruses; it proactively scans for unknown ones too. So, how do scanners really work? The aim of this paper is to reduce some of the confusion around the workings of AV technology, and to clarify what is realistic to expect from AV protection, particularly heuristic analysis.
